probes::EchoPing(3)

NAME
probes::EchoPing - an echoping(1) probe for SmokePing

OVERVIEW
Measures TCP or UDP echo (port 7) roundtrip times for SmokePing. Can also be used as a base class for other echoping(1) probes.

SYNOPSYS
 *** Probes ***
 + EchoPing

 binary = /usr/bin/echoping # default value

 *** Targets ***

 probe = EchoPing
 forks = 10

 menu = Top
 title = Top Menu
 remark = Top Menu Remark

 + PROBE_CONF

 # none of these are mandatory
 timeout = 1
 waittime = 1
 udp = no
 size = 510
 tos = 0xa0
 priority = 6

 + First
 menu = First
 title = First Target
 host = router.example.com

 # PROBE_CONF can be overridden here
 ++ PROBE_CONF
 size = 300

DESCRIPTION
Supported probe-specific variables:

binary
    The location of your echoping binary.

forks
    The number of concurrent processes to be run. See probes::basefork(3pm) for details.

Supported target-level probe variables (see echoping(1) for details of the options):

timeout
    The "-t" echoping(1) option.

waittime
    The "-w" echoping(1) option.

size
    The "-s" echoping(1) option.

udp The "-u" echoping(1) option. Values other than '0' and 'no' enable UDP.

fill
    The "-f" echoping(1) option.

priority
    The "-p" echoping(1) option.

tos The "-P" echoping option.

BUGS
Should we test the availability of the service at startup? After that it's too late to complain.

The location of the echoping binary should probably be a global variable instead of a probe-specific one. As things are, every EchoPing -derived probe has to declare it if the default (/usr/bin/echoping) isn't correct.
